     30'''          Motivation:''' The optimization of NEMO scalability. [[BR]] '''          Status:''' to be started in January 2012 [[BR]] '''          Main tasks:'''[[BR]] * Introduction of a new software layer in the NEMO stack software exploiting numerical optimized and parallel libraries such as  pBLAS, ScaLAPACK and PETSc. [[BR]] * Introduction of a new parallel approach based on the functional parallelism for the tracers and the momentum equations. The parallelism will be based on  spreading: (i) the computation of the tracers and momentum equations and (ii) the computation of the advection, Coriolis, pressure gradient and lateral diffusion terms. [[BR]] * Implementation of a new hybrid parallel approach for exploiting the 3D domain decomposition (MPI on the horizontal domain, OpenMP on the vertical levels) [[BR]] '''          System Reviewer:''' [[BR]] '''          Deadline:'''  2012[[BR]] '''          Priority:'''Medium [[BR]] '''          Principal investigator:''' Italo Epicoco [[BR]]

     39'''          Motivation:'''   Additional diffusion on only the divergent component         of the         velocity could reduce the numerical noise at the high model         topography (step         topography, deep convection, etc.). [[BR]]  '''          Status:''' to be started in January 2012 [[BR]]  '''          Main tasks:''' Add a routine that will apply the divergence filter         in addition to         the horizontal diffusion of the velocity.[[BR]]  '''          System Reviewer:''' [[BR]]'''Science Reviewer:''' '''[[BR]]Deadline: '''2012[[BR]]  '''          Priority:''' High [[BR]]  '''          Principal investigator:'''   Srdjan Dobricic[[BR]]
